Amorphous nickel tungsten tetraoxide （NiWO4） nanostructures （NSs） were successfully synthesized on a flexible conductive fabric （CF） using a facile one- step electrochemical deposition （ED） method. With an applied external cathodic voltage （-1.8 V for 15 min）, the amorphous NiWO4 NSs with burl-like morphologies adhered well on the seed-coated CF substrate. The burMike amorphous NiWO4 NSs on CF （NiWO4 NSs/CF） are employed as a flexible and binder-free electrode for pseudocapacitors, which exhibit remarkable electrochemical properties with high specific capacitance （1,190.2 F/g at 2 A/g）, excellent cyclic stability （92% at 10 A/g）, and good rate capability （765.7 F/g at 20 A/g） in 1 M KOH electrolyte solution. The superior electrochemical properties can be ascribed to the hierarchical structure and large specific surface area of the burl-like amorphous NiWO4 NSs/CF. This cost-effective facile method for the synthesis of metal tungsten tetraoxide nanomaterials on a flexible CF could be promising for advanced electronic and energy storage device applications.

Pancreatic cancer, a highly lethal cancer, has the lowest 5-year survival rate forseveral reasons, including its tendency for the late diagnosis, a lack of serologicmarkers for screening, aggressive local invasion, its early metastaticdissemination, and its resistance to chemotherapy/radiotherapy. Pancreaticcancer evades immunologic elimination by a variety of mechanisms, includinginduction of an immunosuppressive microenvironment. Cancer-associatedfibroblasts interact with inhibitory immune cells, such as tumor-associatedmacrophages and regulatory T cells, to form an inflammatory shell-like desmoplasticstroma around tumor cells. Immunotherapy has the potential to mobilizethe immune system to eliminate cancer cells. Nevertheless, althoughimmunotherapy has shown brilliant results across a wide range of malignancies,only anti-programmed cell death 1 antibodies have been approved for use inpatients with pancreatic cancer who test positive for microsatellite instability ormismatch repair deficiency. Some patients treated with immunotherapy whoshow progression based on conventional response criteria may prove to have adurable response later. Continuation of immune-based treatment beyond diseaseprogression can be chosen if the patient is clinically stable. Immunotherapeuticapproaches for pancreatic cancer treatment deserve further exploration, given theplethora of combination trials with other immunotherapeutic agents, targetedtherapy, stroma-modulating agents, chemotherapy, and multi-way combinationtherapies.

Silicon nanowires（SiNWs） encapsulated with graphene-like carbon sheath（GS） having a void space in between（SiNW@V@GS） are demonstrated for the improved electrochemical performance of Si anode in lithium ion battery. The Si NW@V@GS structure was synthesized by a scalable fabrication method including four successive reactions： metal-catalyzed CVD growth of Si NWs, controlled thermal oxidation, and deposition of the graphitic layer, to form Si NW@SiO2@GS and additional chemical etching of sacrificial SiO2 layer between Si NWs and carbon sheath. During the synthetic process, the thickness of the void spacing was controlled by adjusting the oxidation-dependent process. The well-controlled void space and crystalline graphitic carbon sheath of the SiNW@V@GS structure enable good reversible capacity of1444 m Ahg^（-1） and cycling stability of 85% over 150 cycles.

Dear Editor,Immune-directed therapeutic approaches have changed the paradigm of cancer *** tumor-immune microenvironment[1]is a dynamic milieu consisting of heterogeneous metabolic conditions such as low oxygen,nutrient deficiency,acidity,and interactions between multiple cell *** particular,immune cells in the tumor microenvironment are vulnerable to cellular dysfunctions(because of metabolic reprogramming[2])and engage in intercellular communications with neighboring cells.
